A new report from iPadinCanda.ca suggest Apple could be launching the iPad WiFi model April 24th in Canada. According to the article, Apple has marked the weekend of the 24th a "black out period" for staff. Normally these black out dates are set when Apple is launching a new product and wants to make sure all staff is available and working. During this period no vacations are allowed.
Apple began accepting pre-orders for the iPad 3 weeks before the release date in the US. If you apply the same math to Canada, Canadians may be able to pre-order their iPad Friday April 2nd. We'll keep our fingers crossed for ya!
